At 0:52 the guy has just started narrating an example / story about an experience he had - his expression appears to be remembering quizzically remembering (critical thinking) with either disgust or contempt.
But on secound viewing - I woundered if his example story was in fact made up - it seemed to be too perfect a story to illustrate his point.
Moreover - I noticed the guy moved from side to side in his chair when he started telling his story - to me this felt like weight shifting - possibly a sign of anxiety or uncertainty.
And a few tongue juts appeared - and a long 'thinking' pause during the example story. Some of the detail - the place, the road name, the time of day seems very detailed an specific - like a rehearsed story.
The story speeds up towards the video cut off - which kind of implies a rehearsed story. Children do the same when learning to play a difficult piece of music on the piano. Difficult bit done - then they rush the known easy ending.
